Description

一种摩擦轮牵引传动摆线加工装置A friction wheel traction drive cycloid processing device

技术领域 technical field

本发明涉及一种摩擦牵引传动技术,特别是一种摩擦轮牵引传动摆线加工装置。The invention relates to a friction traction transmission technology, in particular to a friction wheel traction transmission cycloid processing device.

背景技术 Background technique

传统铣削加工中的开槽加工,一般在铣床上采用铣刀进行全刀宽加工。在切削过程中,全刀宽加工对刀具存在诸多的不利因素,如切削热和切屑的排放困难,刀具受到切削负荷大等。随着高速切削技术的快速发展,为了避免刀具的全刀宽加工,先进的数控系统采用摆线加工技术。摆线加工以圆形移动方式沿指定路径运动,逐渐切除毛坯中的材料,从而可避免刀具的全刀宽切削。摆线加工刀具轨迹是一条一阶导数光滑连续的曲线。摆线式高速加工过程中,刀具处于动态的全方位切削,刀体沿周边受力均匀,降低了刀具切削负荷,提高了载荷的稳定性。刀具向前切削材料也伴随着向后的空走刀,这样刀具有充分的时间冷却,同时,还能自动带走切屑,从而大大改善切削条件,提高刀具寿命。摆线加工对于高硬度材料窄槽和型腔的加工具有很大优势。但是采用摆线加工技术,要求数控机床坐标轴不断地往复运动,也就是机床处于震荡之中,不利于机床精度与寿命的保持,特别是对于大型龙门式数控铣床,坐标轴高速往复运动也难以实现。坐标磨床上进行内孔的高精度磨削加工时,一般使用行星电磨头。工件固定在工作台上,砂轮除作高速旋转外,还绕电磨头轴线作行星运动。但是行星电磨头由两套动力装置分别驱动砂轮高速旋转运动和砂轮的行星运动。For slotting in traditional milling, milling cutters are generally used on milling machines for full-width machining. In the cutting process, full tool width machining has many unfavorable factors for the tool, such as cutting heat and chip discharge difficulties, and the tool is subject to a large cutting load. With the rapid development of high-speed cutting technology, in order to avoid full-width machining of tools, advanced CNC systems adopt cycloidal machining technology. Trochoidal machining moves along a specified path in a circular motion, gradually removing material from the blank, thereby avoiding full-width cuts of the tool. The tool path of cycloid machining is a smooth and continuous curve with the first derivative. During the cycloidal high-speed machining process, the tool is in dynamic all-round cutting, and the tool body is evenly stressed along the periphery, which reduces the cutting load of the tool and improves the stability of the load. The forward cutting of the material by the tool is also accompanied by the backward idling, so that the tool has sufficient time to cool down, and at the same time, it can automatically take away the chips, thereby greatly improving the cutting conditions and increasing the tool life. Cycloidal processing has great advantages for the processing of narrow grooves and cavities in high-hardness materials. However, the use of cycloidal processing technology requires that the coordinate axis of the CNC machine tool is constantly reciprocating, that is, the machine tool is in vibration, which is not conducive to the maintenance of the accuracy and life of the machine tool. Especially for large-scale gantry-type CNC milling machines, it is difficult to accomplish. Planetary electric grinding heads are generally used for high-precision grinding of inner holes on coordinate grinding machines. The workpiece is fixed on the worktable, and the grinding wheel not only rotates at high speed, but also performs planetary motion around the axis of the electric grinding head. However, the planetary electric grinding head is driven by two sets of power devices to drive the high-speed rotation of the grinding wheel and the planetary motion of the grinding wheel.

下面结合附图对本发明进行进一步地描述。具有两级行星减速机构的摩擦轮牵引传动摆线加工装置如图1所示,由输入轴1、输出轴16、一级太阳轮2、一级行星轮3、一级行星轮支架5、一级摩擦圈11、二级太阳轮7、二级行星轮6、二级行星轮支架8、二级摩擦圈12、主动轮9、传动轮A13、传动轮B15、从动轮10、中间轴14、外壳4等组成。由一级太阳轮2、一级行星轮3、一级行星轮支架5、一级摩擦圈11组成第一级摩擦轮牵引传动行星减速机构,由二级太阳轮7、二级行星轮6、二级行星轮支架8、二级摩擦圈12组成的二级摩擦轮牵引传动行星减速机构。输入轴1通过锥柄与机床主轴连接。转矩从输入轴1输入,通过第一、二级摩擦轮牵引传动行星减速机构,转换为输出轴16绕输入轴1的回转运动。为使本发明的整体尺寸不致过大,一级行星轮3与二级行星轮6、一级太阳轮2与二级太阳轮7、一级内摩擦圈11与二级内摩擦圈12的直径相差不大,第一级行星减速机构与第二级行星减速机构的传动比相接近。为实现刀具的摆线运动轨迹,输出轴16与输入轴1有一定距离的偏心。机床主轴通过锥柄连接传递给输入轴1的转矩,通过二级摩擦轮传动传递给输出轴16。主动轮9安装于输入轴1上,通过安装于中间轴14上的传动轮A13驱动中间轴14,再由安装于中间轴14上的传动轮B15,驱动安装于装置输出轴16上的从动轮10,最后将输入转矩传递给输出轴16。二级摩擦传动机构的传动比近似为1:1。所述的第一级行星减速机构和第二级行星减速机构之间有一级或多级行星减速机构,以改变输出轴16绕输入轴1的回转速度。The present invention will be further described below in conjunction with the accompanying drawings. The friction wheel traction transmission cycloid processing device with two-stage planetary reduction mechanism is shown in Fig. 1. It consists of input shaft 1, output shaft 16, first-stage sun gear 2, first-stage planetary Primary friction ring 11, secondary sun gear 7, secondary planetary wheel 6, secondary planetary wheel bracket 8, secondary friction ring 12, driving wheel 9, driving wheel A13, driving wheel B15, driven wheel 10, intermediate shaft 14, Shell 4 etc. are formed. The first-stage friction wheel traction transmission planetary reduction mechanism is composed of the first-stage sun gear 2, the first-stage planetary wheel 3, the first-stage planetary wheel bracket 5, and the first-stage friction ring 11. The second-stage sun gear 7, the second-stage planetary wheel 6, The secondary friction wheel traction transmission planetary reduction mechanism formed by the secondary planetary wheel support 8 and the secondary friction ring 12. Input shaft 1 is connected to the machine tool spindle through a taper shank. The torque is input from the input shaft 1, and converted into the rotary motion of the output shaft 16 around the input shaft 1 through the first and second-stage friction wheel traction transmission planetary reduction mechanism. In order to prevent the overall size of the present invention from being too large, the diameters of the first-level planetary gear 3 and the second-level planetary gear 6, the first-level sun gear 2 and the second-level sun gear 7, the first-level inner friction ring 11 and the second-level inner friction ring 12 The difference is not big, the transmission ratio of the first-stage planetary reduction mechanism and the second-stage planetary reduction mechanism are close.

摩擦牵引传动机构要求相互接触的摩擦轮之间有足够的正压力,以形成高压牵引油膜,达到足够的牵引传动效率。以下两种方法可以在摩擦轮之间提供足够的正压力:(1)对称行星滚轮摩擦牵引传动装置普遍采用锥形滚道,通过调节面对面或背靠背配置的锥形滚道的轴向移动,来产生径向位移,从而提供牵引或摩擦传动所需要的正压力。行星滚轮牵引传动的压力自动加载机构采用滚珠V型槽或端面凸轮机构,它们的工作原理基本相同。本发明中,一级太阳轮2、二级太阳轮7、主动轮9、从动轮10分别是由上下两部分及中间垫圈组成的。上下两部分都带有一定的斜度,调节两部分之间的轴向位移可以控制一级太阳轮2与一级行星轮3、二级太阳轮7与二级行星轮6之间的径向位移,继而调节过盈量,从而为摩擦传动提供正压力。(2)各级摩擦轮采用胀紧套,通过调节胀紧套的胀紧螺钉控制摩擦轮轮廓的径向位移,达到提供正压力的效果。本发明装置中,一级太阳轮2、二级太阳轮7、主动轮9、从动轮10、传动轮A13、传动轮B15、一级行星轮3和二级行星轮6都可以在其外部安装胀紧套。The friction traction transmission mechanism requires sufficient positive pressure between the friction wheels in contact with each other to form a high-pressure traction oil film and achieve sufficient traction transmission efficiency. The following two methods can provide sufficient positive pressure between the friction wheels: (1) Symmetrical planetary roller friction traction drives generally use tapered raceways, by adjusting the axial movement of the tapered raceways arranged face-to-face or back-to-back, to Radial displacement is generated to provide the positive pressure required for traction or friction transmission. The pressure automatic loading mechanism of planetary roller traction transmission adopts ball V-shaped groove or end face cam mechanism, and their working principles are basically the same. Among the present invention, the primary sun gear 2, the secondary sun gear 7, the driving wheel 9, and the driven wheel 10 are respectively composed of upper and lower parts and an intermediate washer. The upper and lower parts have a certain slope, adjusting the axial displacement between the two parts can control the radial direction between the primary sun gear 2 and the primary planetary gear 3, the secondary sun gear 7 and the secondary planetary gear 6 Displacement, and then adjust the amount of interference, so as to provide positive pressure for friction transmission. (2) The friction wheels at all levels use expansion sleeves, and the radial displacement of the friction wheel profile is controlled by adjusting the expansion screws of the expansion sleeves to achieve the effect of providing positive pressure. In the device of the present invention, the primary sun gear 2, the secondary sun gear 7, the driving wheel 9, the driven wheel 10, the driving wheel A13, the driving wheel B15, the primary planetary wheel 3 and the secondary planetary wheel 6 can all be installed outside it Tightening sleeve.
